In 10 years, everyone will have a 3D printer in their house. Your friend will say, “Let’s go, hurry up” and you’ll go, “Wait, my shoes haven’t finished printing yet.” In 20 years, you’ll be able to print a new kidney. You’ll have a machine that prints your genome with proteins that are right for your body. 3D printers will change how we make things, how we fix and heal things. To eat beef and wear leather, you need a lot of land and water for cows. In the next 20 years, we’ll be able to print beef and leather instead. Real talk.
